Signs Your Senior Dog Has Arthritis (and How to Keep Them Comfortable)

If your older dog takes a moment to unfold from her bed, hesitates at the bottom of the stairs, or lags behind on the walk she used to lead, that is worth paying attention to. The signs of arthritis in dogs are often written off as normal aging, but slowing down is usually pain, and pain can be treated. Osteoarthritis is a chronic, progressive joint disease that commonly affects dogs, and while there is no cure, there are several ways to slow it down, control pain and protect mobility.

This guide is for owners of middle-aged and senior dogs who suspect something has changed. It covers what to look for at home, what your vet can do, and which treatments genuinely help.

What are the early signs of arthritis in dogs?

Arthritis pain builds slowly, so the first clues are subtle. Look for patterns rather than single bad days.

• Slowness to rise, especially after a long rest, often pushing up with the front legs first and hauling the back end after
• Difficulty going up or down stairs, or reluctance to jump into the car or onto furniture
• Doing less: shorter walks, less running, less enthusiasm for exercise
• A limp or a change in the way she moves, which may come and go
• Stiffness that eases after a few minutes of walking
• Sitting in odd, lopsided positions, or lying down when asked to sit
• Muscle loss over the hips or shoulders, so the hind end looks narrower

Sitting "side-saddle" instead of square, with hocks, knees and hips out of line, can be an early sign of joint discomfort before any lameness appears. So can always lifting one front leg while eating from the floor. These habits are easy to read as quirks of personality.

Behaviour changes owners often miss

Chronic pain changes personality as much as movement, and the person who knows the dog best is usually the first to notice.

• Loss of interest in play, toys or greeting people
• Irritability or even aggression when touched, lifted or jostled
• Restlessness at night, or new sleeping spots and positions
• A drop in appetite
• Reluctance to be handled, or flinching over one particular area
• Behaviour read as laziness, anxiety, or a sudden fear of stairs or the car

Why do dogs hide joint pain so well?

Lameness is the classic sign, but it is often less obvious than you would expect, not only in early disease but even in advanced disease affecting both sides. A dog with two sore hips or two sore elbows redistributes weight onto whichever limbs hurt less, which flattens out the limp while quietly straining the other legs.

There is a second problem: dogs are good at compensating, so they simply modify what they do rather than showing you they hurt. And the vet clinic is the worst place to catch it, because excitement in the consulting room can mask stiffness, slowness to rise and mild lameness. Screening owners with a simple arthritis checklist has been shown to nearly double the number of dogs identified with osteoarthritis pain, which tells you how much goes unnoticed.

The practical takeaway: do not wait for obvious lameness. If your dog has stopped doing two or three things she used to do, that is enough reason for a check-up.

Which dogs are most at risk?

Age matters, but so does history. Arthritis usually follows something that was already going on in the joint. The joints most often affected are the elbow, hip, hock and knee.

• Hip or elbow dysplasia, kneecap (patella) problems, or cruciate ligament damage in the knee
• Any previous joint injury, fracture or joint surgery
• Being overweight, which loads joints mechanically and adds low-grade inflammation, because fat is an active tissue that releases inflammatory signals
• Breeds with a genetic predisposition, and working or sporting dogs exposed to repetitive high-impact loading
• Entering the senior life stage

Worth knowing: arthritis is not only a senior disease. The average age at diagnosis is around ten and a half years, yet studies of dogs aged eight months to four years have found radiographic arthritis in roughly 40%, and most of those with detectable joint pain were receiving no treatment at all.

How does a vet diagnose arthritis in a senior dog?

A hands-on orthopaedic exam is the core of it. Your vet will watch your dog stand, sit, walk and trot, check how evenly she bears weight, then feel each joint for swelling, heat, thickening, grating, reduced range of motion and pain, comparing left with right and palpating the muscles for wastage or spasm.

X-rays help confirm the diagnosis and rule out other causes of a painful limb, such as joint infection, immune-mediated joint disease or bone tumours, which need completely different treatment. But radiographs and suffering do not track each other neatly. International consensus guidance is that treatment should be based on clinical signs rather than radiographic ones, and the same group recommends combining a validated owner questionnaire, your own impression of your dog's pain, and a full physical examination to work out how severely she is affected. Advanced imaging such as CT or MRI picks up changes earlier than X-rays, and is used in selected cases.

Bring your observations. A short phone video of your dog getting up from rest and walking away is often more informative than five nervous minutes at the clinic. If long-term medication is likely, expect blood and urine tests first, then repeated periodically.

How can I keep my arthritic dog comfortable at home?

Home care is not the soft option. Weight, exercise and environment do a large share of the work.

Get the weight off

Keeping your dog lean is the single most powerful thing you can do. A body condition score of about 4.5 out of 9 is the target, achieved mainly by controlling calories: you should feel the ribs easily under a thin layer of fat, with a waist visible from above. In overweight dogs with hip or elbow arthritis, losing as little as 6% to 18% of body weight has produced measurable improvements in lameness. Ask your vet for a target weight and a measured daily allowance, weigh the food rather than scooping it, count treats, and book regular weigh-ins, since sticking with the plan is the hardest part.

Make the house easier to move around

Adapting the environment is the first layer of any physiotherapy plan, and it costs almost nothing.

• Lay non-slip rugs or mats along the routes she uses most, especially on smooth floors
• Use a ramp for the car, and for the sofa or bed if she is allowed up
• Manage stairs: block them off when you cannot supervise, or use a ramp
• Support a wobbly dog with a harness that has a handle

Rethink exercise rather than stopping it

Rest does not help arthritic joints. Muscle is what stabilises them, and it disappears fast in a dog who has stopped moving. Regular, controlled, low-impact exercise is recommended for arthritic dogs: several short lead walks a day on even ground, at her pace, rather than one long one. Combining a weight loss diet with physiotherapy works better than dieting alone.

Swimming and underwater treadmill work suit many dogs. Water takes weight off sore joints so a weak or painful dog can exercise for longer, while still providing resistance to build muscle, and swimming programmes have improved joint mobility and reduced pain on palpation in dogs with hip arthritis. What to cut back: repetitive ball throwing, skidding turns on hard surfaces, jumping in and out of cars, and long weekend hikes after a quiet week.

Flare-ups happen. If your dog is suddenly much stiffer or lamer, keep her quiet for a day or two, and call your vet rather than waiting it out if she does not return to her usual self.

Which treatments actually help?

Arthritis cannot be cured, so the aim is to control pain, keep muscle and mobility, and protect quality of life. Guidelines favour a proactive, multimodal plan over relying on one thing, because controlling the pain is what makes weight loss and exercise possible in the first place.

• Prescription pain relief: Anti-inflammatory drugs licensed for dogs (the veterinary NSAIDs) and monthly anti-nerve growth factor antibody injections are both considered appropriate first-line options for arthritis pain. A trial comparing the antibody bedinvetmab with the NSAID meloxicam found both equally effective, with fewer adverse events reported in the antibody group. Which suits your dog depends on her other health problems, so this is a conversation with your vet.
• Additional pain medicines: Where one drug is not enough, vets may add medicines such as gabapentin or amantadine. Tramadol, by contrast, has been shown not to control arthritis pain in dogs and is not recommended as routine therapy.
• Physiotherapy and rehabilitation: A qualified veterinary physiotherapist can build a tailored programme, teach you home exercises and offer hydrotherapy. Supervised exercise tends to work better than unsupervised.
• Nutrition: Diets formulated for joint disease contain higher levels of marine omega-3 fatty acids, sometimes with antioxidants and other joint compounds. Ask your vet whether a therapeutic diet fits your dog's weight plan.
• Supplements: Glucosamine and chondroitin are widely sold and widely used, but the strength of the evidence behind them is debated. They are worth discussing, not worth relying on in place of weight control and proper pain relief.
• Acupuncture, laser and shockwave therapy: Used as add-ons for individual dogs alongside the measures above.
• Surgery and joint injections: For an underlying problem such as a ruptured cruciate ligament, or a single badly affected joint, surgery or intra-articular injections may change the picture. Ask whether referral makes sense.

Anything new needs review. If your dog receives a monthly pain injection, watch for and report clumsy walking, weakness, tremors, seizures, vomiting, poor appetite or increased drinking, all of which have been reported after treatment. A dog who suddenly feels better may also overdo it, so agree an exercise plan with your vet before letting her loose. Reports of unusually fast joint deterioration in some treated dogs mean this class of drug is still under active safety monitoring, and combining it long term with anti-inflammatories is not fully established.

What should I never give my dog for joint pain?

Give only what your vet has prescribed for this dog, at the stated dose. Do not raid your own medicine cabinet, and do not use leftovers from another pet.

Two specific traps are worth naming. Combining an anti-inflammatory with a second anti-inflammatory, a steroid, or another drug that irritates the stomach raises the risk of gastrointestinal ulceration and should be avoided. And dogs on long-term anti-inflammatories need periodic blood tests to check liver and kidney function, with the dose reviewed if anything looks off.

If your dog has swallowed a medicine not prescribed for her, phone your vet or an emergency clinic straight away and say what and how much. Do not wait for symptoms.

When to call the vet

Book a routine appointment if you have noticed stiffness, reduced stamina, reluctance on stairs, or a limp lasting more than a few days. Earlier is better: outcomes are better when arthritis is diagnosed and managed before it has progressed far.

Seek same-day or emergency care if your dog:

• Suddenly cannot bear weight on a leg, or the leg looks deformed
• Cannot stand or get up at all, or is scuffing her toes and dragging a hind leg
• Has a hot, swollen, very painful joint, especially with a fever or being off her food
• Is crying out, panting hard, trembling or unable to settle
• Becomes wobbly or weak in several limbs, or has a seizure
• Vomits, has diarrhoea, goes off her food, or passes black tarry stools while on medication. Stop the medicine and phone your vet.

Keeping track over time

Arthritis needs review, not a single prescription. Plan a recheck within a few weeks of starting anything new, then at intervals your vet sets, with weight checks and blood tests as advised. In between, keep a simple diary: is she getting up more easily, walking further, greeting you again, sleeping through the night? Short videos every few weeks give you an honest comparison, because day-to-day memory is unreliable.

One more thing worth saying out loud. Caring for a dog in chronic pain is genuinely hard on owners, and around half of owners of arthritic dogs carry a significant caregiver burden. If you are struggling, or wondering how much longer this is fair on her, say so at the appointment. That is a conversation your vet should be having with you.

Most dogs with arthritis have good years ahead when the pain is properly managed. Take the small signs seriously, keep her lean and moving, and treat your vet as a long-term partner in the plan rather than a last resort.
